fossilisation

how?

 

[spiderfan44]

how?

bcuz i think thats when there was the first multicellur organisms who could be preserved well.

 

[spiderfan44]

the only other option was oxygen in atmosphere and that happened 3.5 billion years ago i think

 

[Tanay07]

so what ans was that B or C?

 

[spiderfan44]

b i think?

 

[Tanay07]

i still reckon its diversification of multicellular life but ig we'll see in the upcoming days

 

[jlaaaz]

i said ocean circulation

me too

 

[jlaaaz]

Like some characteristics in the ediacaran period?? i think.. I chose the distrubution of mutilcellular lief, cuz it cant have been the oxygenation of the earth since it happened 3.5billion years ago? right?

i think i did oxygenation bc on the geological timescale the ediacaran is part of neo-proterozoic and that was the first oxygenation event if i'm pretty sure??????? it can't be fossilisation bc they were soft bodied right? that one was a blur

 

[jlaaaz]

people said it was hard

i really liked it idk maybe that means i did bad? i didn't study for it bc i had cafs in the morning and i do 12 units (ees won't count to my atar) so i crammed in the 40 minute period between the exams but all you needed was to be an environment advocate to write about most of the questions imo
